EPSG:7058

Hughes 1980

Attributes

Unit: metre

Data source: OGP

Information source: US National Snow and Ice Data Center

Revision date: 2006-09-22

Remarks: Used in US DMSP SSM/I microwave sensor processing software. Semi-minor axis derived from eccentricity=0.081816153. Semi-major axis (a) sometimes given as 3443.992nm which OGP suspects is a derived approximation. OGP conversion assumes 1nm=1852m exactly.
